Can ChatGPT read my website?

ChatGPT and other AI platforms fetch your page without running JavaScript. If your most important content only loads client-side, for example a React app without server-side rendering, ChatGPT often sees an almost empty page. The scan checks exactly that.

Does GPTBot render JavaScript?

No. GPTBot, OAI-SearchBot, ClaudeBot and PerplexityBot do not run JavaScript; they only read the HTML your server returns right away. Server-side rendering (SSR) or static generation (SSG) is therefore crucial for your AI visibility.

How do I give AI bots access through robots.txt?

Add explicit Allow rules for OAI-SearchBot, GPTBot, PerplexityBot and Google-Extended. The scan shows whether one of these AI crawlers is currently blocked in your robots.txt, often by accident.

What is llms.txt and do I need it?

llms.txt is a text file in the root of your website that tells AI platforms in plain language who you are and which pages matter. It is not a proven ranking factor, but it is a free, low-effort signal. In GreatCompany you generate it in one click.

How is this different from regular SEO?

SEO is about your position in the blue links of Google. This scan is about GEO (Generative Engine Optimization): whether AI search engines can read and cite your content. They partly overlap, but AI has its own requirements, such as readability without JavaScript.

Is this the same as the ChatGPT check?

No. The ChatGPT check tests whether your business is mentioned in AI answers. The technical scan looks under the hood: can AI read your website properly at all? That is often the first reason a business is not mentioned.

The scan is free and part of the free AI visibility report. GreatCompany is opening in the US: join the waitlist and you are first in line. Fixing issues step by step happens in GreatCompany.

Can AI even read your website?

Some websites block AI bots. Many more hide their content by accident in code AI does not read. The scan shows whether ChatGPT, Perplexity and Google AI can read and cite your pages, and which of the six parts hold your visibility back.

What is a technical AI scan?

A technical AI scan, also called a GEO scan (Generative Engine Optimization), checks whether AI platforms such as ChatGPT, Perplexity, Google AI Overviews and Gemini can fetch, read and cite your website. Classic SEO is about your position in Google. This scan answers a simpler but harder question: does AI see your content at all? If not, you never get mentioned in AI answers, however good your offer is.

Why your website might be invisible to AI

Almost no business chooses to be invisible to AI. It happens by accident, usually for a technical reason like these:

AI does not read JavaScript

Crawlers such as GPTBot and OAI-SearchBot do not run JavaScript. If your content only lives in a React or Vue app without server-side rendering (SSR), they see an empty page.

robots.txt blocks AI bots

Some sites still block GPTBot, OAI-SearchBot or PerplexityBot by accident, a leftover from the "block everything" period of 2023. Then AI is not even allowed to fetch your content.

No structured data

Without schema.org markup (Organization, FAQPage), AI misses the context to recognize your business correctly and cite it as a reliable source.

No llms.txt

An llms.txt file tells AI platforms in plain text who you are, what you do and which pages matter. Without it, AI has to work it out alone. The steps are in how AI crawlers read your site.

What the free scan checks

The scan covers six parts that together decide whether you can be found in AI search engines:

Readability for AI (SSR/SSG): Is your content in the source HTML, or only after JavaScript runs?
Access for AI crawlers: May GPTBot, OAI-SearchBot, PerplexityBot and Google-Extended read your site, and is your sitemap right?
Structured data: Organization, WebSite, Breadcrumb and FAQPage schema for context and citations.
Entities and authority: sameAs links (LinkedIn, Wikidata) and E-E-A-T signals.
Shareability: Open Graph and Twitter tags, so AI summarizes your content well.
Machine-readable signals: llms.txt, visible dates and feeds.

Who is this scan for?

For every business that wants to be found in AI answers: small and mid-sized service businesses, online stores, local businesses, SaaS companies and marketing agencies. Want to know after the technical scan whether you really get mentioned for customer questions? Read about the ChatGPT visibility check.
